[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The present invention provides a post-processing and equipment maintenance system for an automated production line to solve the problem in the prior art that a failure of an automated production line requires manual intervention and affects the production rhythm. Figure 1 , including a conveyor line and a workbench 1, the conveyor line transports the workpiece to the workbench 1; also includes a main working mechanism and a post-processing and maintenance mechanism; the above-mentioned main working mechanism is arranged on the outside of the workbench 1, and the above-mentioned main working mechanism performs production work on the workpiece on the workbench 1; the above-mentioned main working mechanism includes a collaborative robot 2, a visual system 3 and a tightening system 4; the above-mentioned post-processing and maintenance mechanism includes an automatic nail cleaning mechanism 5, and the above-mentioned automatic nail cleaning mechanism 5 is used to handle error problems during bolt operation.

[0024] In one embodiment, the visual system 3 and the tightening system 4 are located on the collaborative robot 2 .

[0025] The visual system 3 includes a camera.

[0026] The tightening system 4 comprises a tightening gun.

[0027] In the specific implementation, the workpiece is transported on the conveyor line, and the picking mechanism takes the brake disc from the feeding mechanism. Then the picking mechanism translates the workpiece to the detection mechanism for detection. After the detection is completed, it is transported to the bolt tightening system 4, and the PLC controller controls the workpiece to be transmitted to the workbench 1 corresponding to the bolt tightening system 4. After the workpiece arrives at the corresponding workbench 1, the main working mechanism works, wherein the camera first captures the specific position of the workpiece, and then the tightening gun performs the bolt tightening work. After the operation on the workbench 1 is completed, it is transported to the next workstation through the conveyor line for normal work; during the operation of the tightening gun, if there is an error problem such as screw falling, the PLC controller controls the automatic nail cleaning mechanism 5 to work, and handles the fault on the workbench 1. For example, if the screw falls, the screw will be clamped away, and the screw to be tightened will be prepared; after the tightening work of the workpiece is completed, the flipping and transverse movement mechanism flips the workpiece and then moves it transversely, and finally it is transported to the next workstation by the conveying system.

[0028] The utility model is provided with an automatic nail clearing mechanism 5. When a bolt tightening error occurs during the workpiece production process, the automatic nail clearing mechanism 5 automatically processes and solves the error, thereby reducing manual line stop intervention.

[0029] In one embodiment, the post-processing and maintenance mechanism further includes a calibration mechanism 6 , and the calibration mechanism 6 is used to adjust the accuracy of the collaborative robot 2 .

[0030] After the collaborative robot 2 works repeatedly for a long time, deviation may occur. The PLC controller starts by controlling the calibration mechanism 6 to call back the deviation of the collaborative robot 2, so that the collaborative robot 2 is calibrated regularly.

[0031] In one embodiment, the post-processing and maintenance mechanism further includes a camera calibration plate 7, and the camera calibration plate 7 is used to calibrate the camera.

[0032] The camera is prone to loosening after long-term use; the camera calibration board 7 is used to start and adjust the camera to quickly recover, preventing the camera from moving and affecting the normal operation of the workstation;

[0033] In one embodiment, the post-processing and maintenance mechanism further includes a torque calibration mechanism 8, and the torque calibration mechanism 8 is used to perform torque calibration on the tightening gun.

[0034] It is necessary to regularly calibrate the torque of the tightening gun, for example, half a year is a cycle, the torque calibration mechanism 8 is controlled to start, and the torque of the tightening gun is calibrated once every six months;

[0035] The tightening gun is provided with a sleeve.

[0036] The above-mentioned post-processing and maintenance mechanism also includes an automatic sleeve replacement mechanism 9, and the above-mentioned automatic sleeve replacement mechanism 9 is used for periodically replacing the above-mentioned sleeve.

[0037] When the number of times the sleeve on the tightening gun is used exceeds a certain value, the PLC controller records the number of times the sleeve is used, for example, when the sleeve is used 100,000 times, the automatic sleeve replacement mechanism 9 is started to replace the sleeve; at the same time, when tightening operations are required on different types of workpieces, the automatic sleeve replacement mechanism 9 can also be started to replace the sleeve, so that the sleeve matches the workpiece, so that the tightening gun can adapt to the tightening work of different types of workpieces.

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
